. Be't known that I, JAMES MASKER, a citizen" of the UnitedSta-tes,residing at Hammond, 1n the county of Lake, State of Indiana, haveinvented a new and useful'lmprovement in Railway-Car Roofs, of which thefollowin is a full, clear, and exact de improvements in car'roofs ofthat classconig outside roofs and particularly contemplates theprovision of a construction in; which the main elements thereof willsecurely hold in water-tight relation while allowing the samesuflicientj play to overcomethe tendency of the same to buckle and bendunder the eifect "of the 1 sides in the following strain put upon them.

My invention further and specificallyrefeatures of construction andarrangement as willfbe hereinafter described with reference to theaccompanying drawings forming a part of this specification, in whichlike numerals are used to --designate like parts throughout the severalfigures, and in which,

Figure I is a perspective view of a portion 1" of acar roof constructedin accordance with my invention, Fig. 2 is aperspective viewof one ofthe intermedlate roof plates, Fig.

I 3' is a similar view of one of the end roof plates, Fig. 4tisabottomplan view of one of the carlines, Fig. 5 is a side elevation ofthe same, Fig. 6 is an end view of the same, Fig. 7 is a perspectiveview of one of the plate securing cli s, Fig. 8 is a similar view of oneof the car ine end caps, Figs. 9, 10

and ,11 are perspective views of adjoining sections of the ridge-pole,Fig. 12 is a perspective View of the ridge. pole securing plate. Fig. 13is a sectional View taken through one of the'flanges of the roof plateson an enlarged scale, and Fig. 14L is a transverse sectional view takenthrough my improved roof as a whole.

In the practical embodiment of my inven-' tion and with particularreference to the accompanying drawings 1 provide a rid e pole comprismgdetachable sections 13., i cl B the intermediate section B beingg'ovided with mortised and reduced ends B. The outer endsB of the-end pi3';

and B. respectively, engaging with the res actively mortised and reducedadjacent an S3 and B eff the outer pieces B and seatsDaz -gate.

and B are also .reduce( the ridge pole cap plates Q fmvhich' are boltedor otherwise secured to: the-ends :oi tl'1e The pieces B, B? and B-forming the idge pole are further provide "1th;longitudinal undercutchannels )3 an with openings, 115

receive thereon communicating with saiduclfiannels 1 Bh ufor a thereception of the reduced ends E of the carlines E The carlinesE are alsore.- duced upon their outer ends E to receive thereover the carline endcaps C bolted or otherwise attached to the car sides. The carlines E arefurther provided with longitudinal parallel channels E for a purpose tobe hereinafter described.

A plurality of metallic plates .1) have flanges D bordering the same,said flanges having the edges thereof curled about metallic rods 1) tostrengthen the same. The side flanges and one end flange are constructedupstanding from their respective plates andhave their abutting endssoldered together, said end flange being adapted to beheld within thechannels B of-the ridge pole, and said side flanges'being adapted to beheld within the channels'E of the carlines E when said. plates D areinserted therebetween thus forming with said ridge pole and saidcarlines, a movable though perfectly water-tight joint. The descriptionof the plates thus far applies to the inter mediate plates 1) while theend plates 1) and D have .only their inner end and side flanges Dupstanding, the remaining flanges D like the outer end flanges D of theplates D being turned down upon the car sides and ends, and securedthereto by metallic clips F engagingthe curled edges of the said flangesD and secure to the car.

In securing the ridge pole upon the car I provide the piecesiB, B and Bwith longitudinal beveled lower edges B adapted to slidably fit withinthe undercut channel A of securing plates A adapted to be bolted to thetop of the car thus efi'ectuallycovering the bolt openings andvpreventing moisture entering the car by this means. I also cast thepieces B, B and B with upstanding ledges G which may be utilized as.sleepers forthe well known walking boards (not shown).

From the foregoingv description it will be apparentthat I provide anovel construction 0 an outside roof for cars in which the eralelementsfare securely held in place and form perfectly water-tightjoints while ing sullieient i'i'iovemcnt With relation to one another toovercome the tendei'icy of breaking apart and of the metallic platesbuckling and bending under the strain imposed upon them by the movingcar.

l-laving thus fully described my invention, 1 claim:

l. The combination in a car roof, of a 'thereo'r', substantially asdescribed.

The combination in a car roof, of a ridge pole, and means for securingthe same comprising a clamping plate rigidly secured upon the car andprovided with a channel adapted to receive and hold said ridge poletherein, substantially as described.

3. In a car roof of the cl'iaracter described, the combination of aridge pole formed in length by a plurality of relatively engagingsections, and dovetailed gulde plates secured upon the car for clampingeach of said sections, substantially as described.

In witness whereof I hereunto afi'ix my signature in presence of twowitnesses this 8th day of April, 1907.
